Blind adaptive principal eigenvector beamforming for acoustical source separation

For separating multiple speech signals given a convolutive mixture, time-frequency sparseness of the speech sources can be exploited. In this paper we present a multi-channel source separation method based on the concept of approximate disjoint orthogonality of speech signals. Unlike binary masking of singlechannel signals as e.g. applied in the DUET algorithm we use a likelihood mask to contro...

Adaptive whole Earth tomography

[1] An approach for seismic tomography is presented which allows the parameterization to be refined during the inversion. The objective is to use the data to refine the mesh and the velocity model together, and hence both are considered part of the solution. Some simple rules are used to identify the volumes of a three-dimensional model in need of refinement. The self-adaptive parameterization ...

Solar tomography adaptive optics.

Conventional solar adaptive optics uses one deformable mirror (DM) and one guide star for wave-front sensing, which seriously limits high-resolution imaging over a large field of view (FOV). Recent progress toward multiconjugate adaptive optics indicates that atmosphere turbulence induced wave-front distortion at different altitudes can be reconstructed by using multiple guide stars. To maximiz...

Practical adaptive quantum tomography

We introduce a fast and accurate heuristic for adaptive tomography that addressesmany of the limitations of priormethods. Previous approaches were either too computationally intensive or tailored to handle special cases such as single qubits or pure states. By contrast, our approach combines the efficiency of online optimizationwith generally applicable andwell-motivated data-processing techniq...
